CORN-SHE'LLER.

Specification of Letters Patent No, 19,915, dated April 13, 1858.

To all whom it may concern:

Bev it known that I, AUGUSTUS B. DAVIS, of the city of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Corn-Shellers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention consists in combining an endless band or chain of toothed plates with an angular barred grating, in the manner fully set forth hereafter, for the purpose of stripping the kernels from ears of corn in a rapid and effectual manner.

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawing, which forms a part of this specification; Figure 1 is a side elevation of my improved cornsheller; Fig. 2 a sectional elevation of the same; Fig. 3 a ground plan, with all the operating parts above the grating removed; Fig; 4 a transverse section on the line 1, 2, (Fig. 2); Fig. 5 an enlarged view, showing a mode of constructing an endless chain of toothed plates.

Similar letters refer to similar parts throughout the several views.

The framework of themachine consists of the two side pieces A and A, the transverse bars B and B and the legs G, C, C, C. In front of the machine and between the sidepieces A and A is the shelf D, for receiving the ears of corn. Two shafts E and F are hung in suitable boxes (1, a, a, a, secured to the opposite side pieces, the shaft F near the front, and the shaft E at the back of the machine.

G, G, G, G, &c. is a series of metal plates furnished with'pointed teeth, and secured to the endless bands 0, e, in close proximity to each other. The ends of these toothed plates pass over the pulleys H and H, two of which are secured to the shaft E, and two to the shaft -F. These pulleys are octang'ular, or have any convenient number of sides, providing each side is as long as the plates G are wide. Flanges h on these pulleys serve to maintain the toothed plates in their proper position laterally. Inside of the opposite side pieces A and A are secured strips I, on the upper curved edges of which the ends of the toothed plates are caused to bear, by means of the rollers K, K, which are hung to the spindles L, the latter turning in the opposite side pieces A and A, and being pressed down by means of the springs M, M, one of which is situatedon each side of the machine. The endless band of toothed plates, as it is caused to traverse over the pulleys, assumes the curved form represented in Fig. 2.

N is an arched grating, secured to the frame of the machine, and having two sets of angular bars with sharp upper edges, one set being placed at a contrary angle to that of the other, as seen in Fig. 3. This grating is so situated, as to be in closer proximity to the toothed plates at the back of the machine than in front.

Instead of securing the toothed plates-to an endless band, I propose, in some instances, to hinge them together, as seen in Fig. 5, so as to form of themselves an endless chain.

The machine may be turned by hand, or by a strap passing over a pulley secured to one of the spindles E or F, the toothed plates being caused to traverse in the direction of the arrow (Fig. 2). The ears of corn are placed on the shelf D, down which they slide until caught by the traversing plates G, which draw them over the grating N. The ears, having a tendency to traverse the grate at the same angle as the bars, must roll over from side to side, and, during their course over the grating, must be submitted to the action of the toothed plates, which effectually strip the kernels from the cob. Thus an ear, presented to the machine at :20, will roll over, following the bars as a guide until it arrives at y. From this point the bars are placed at a reverse angle, which the ear follows with a rolling motion, until it makes its exit at .2, entirely deprived of its kernels by the plates G, which have been moving rapidly in a tween. the traversing plates and the grating tially as, and for the purpose herein set 10' forth.

In testimony whereof, I have signed my name to this specification before two subscribing witnesses.
